Safety Precautions – Symbols

A suitable surge protector must be used in order to ensure that the installation site meets the requirements specified for overvoltage category II.
Check the specified nominal voltage on the serial plate before placing the instrument into service.
Observe maximum pulse output voltage.
When wiring the instrument, make sure that the connector cables are not damaged, and that they are voltage-free.
If it can be assumed that safe operation is no longer possible, the instrument must be immediately removed from service (disconnect input voltage!).
Safe operation can no longer be relied upon if the instrument demonstrates visible damage.
The instrument may not be placed back into operation until troubleshooting and repair have been performed, and calibration and dielectric strength have been tested and approved at our factory or by an authorized service center.
Balancing, maintenance or repair may only be carried out by trained personnel who are familiar with the dangers involved.
terminals of the U1614 power pack module may only be disconnected or connected in the current and voltage-free state!
During operation when auxiliary power is active, the U1614 power pack may not be plugged into or unplugged from the TBUS!
During operation when auxiliary power is active, neither the U1604 basic module nor any other S0 modules may be plugged into or unplugged from the TBUS.
Opening the housing of the U1614 power pack during operation is impermissible! The fuse may only be replaced in the voltage-free state.
The TBUS may only be used to connect ECS components. Any combination with non-system devices with similar backplane connection is impermissible.

Introduction

The new modular concept of the SU1604 summator permits space-saving setup of an energy control system in accordance with actual requirements. Thanks to strict software compatibility with U1600 and U1601/2/3 systems which are already in use, these can be easily replaced or expanded.
A summator can be set up using the following modules:

U1604 basic module with the following interfaces: 1 ea. RS 232 (COM-1), 1 ea. RS 485 (COM-2), ECS LAN left + right, LON, 2 ea. S0 relay output
U1614 power pack module with status relay for supplying power to all components via the TBUS and an additional 24 V DC output (max. 5 W) – overall output power amounts to 20 W
U1624 S0IN12 input module with 12 S0 compatible inputs (max. 6 modules, max. 64 S0 inputs)

Connector Terminals, TBUS and Power Supply

Connector Terminals

All signals are fed to the respective module via screw terminals which can be unplugged (3, 4 or 5-pole). This assures trouble-free replacement in the event that servicing is required.

TBUS

The individual components are connected to each other via the so-called TBUS.
The TBUS is laid out as a 5-conductor system and distributes 24 V DC supply power and signals from the TBUS communications interface (RS-485) to all components. The fifth conductor is used to indicate status. One or two corresponding TBUS plug connectors are included with each module. These TBUS parts (width: 17.5 or 22.5 mm) are snapped into the DIN top-hat rail in the fully assembled state before the module is plugged on.

Attention!
During operation when auxiliary power is active, neither the U1604 basic module nor any other S0 modules may be plugged into or unplugged from the TBUS.

Please note: The U1614 power pack module with an overall width of 35 mm requires two 17.5 mm TBUS plug connectors, and all other devices require one or two of the 22.5 mm TBUS plug connectors.

Power Supply

There are two power supply options:
– Via the U1614 power pack module

Attention!
When power is supplied as auxiliary energy via the TBUS, the U1614 power pack module may not be plugged on!
– Via the external 24 V auxiliary power terminal (see photo below)
If the 24 V auxiliary power terminal is used, no status relay is available.
In order to make a status output available for this configuration, the status of the U1604 basic module can be mapped to relay 1 or 2.
The status is mapped via a so-called attribute.
Attributes are stored to non-volatile memory at the U1604 basic module and are not deleted in the event of a simple or an extended master reset.

Activating status mapping to relay 1 or 2:
STATRELMAP attribute = 1 (relay 1 or 2)
Deactivating status mapping (default):
STATRELMAP attribute = 0

COM Settings

COM1 (RS 232 full-duplex) default settings:
Baud rate: 115,200 baud (9600, 19,200, 38,400, 57,600, 76,800, 115,200, 230,400, 460,800, 921,600)
Handshake: RTS/CTS (-, RTS/CTS, XON/XOFF)
Parity Off (off, even)
Mode: ECL (OFF, ECL, DCF …)

COM2 (RS-485 half-duplex) default settings:
Baud rate: 115,200 baud (9600, 19,200, 38,400, 57,600, 76,800, 115,200, 230,400, 460,800, 921,600)

Handshake: —
Parity Off (off, even)
Mode: ECL (OFF, ECL, DCF …)
Caution: Changes to the settings may render the instrument unusable, insofar as faulty settings cannot be corrected via another correctly functioning interface.
Tip: The COM port for FTDI-based USB-RS485 converters can be permanently assigned in the device manager, and management of two or more virtual COM ports can thus be optimized.

TCP/IP

In addition to the COM-1 and COM-2 ports, ECL inputs are also available via TCP/IP. After opening one of the TCP-IP sockets from a PC, characters can be transmitted in both directions, as if connection had been established via a COM port (like a COM server).

Default IP settings and ports:
IP address: 192.168.0.50
Net mask: 255.255.255.0
Gateway: 192.168.0.1
COM-4 port: 5004 (mode = ECL)
COM-5 port: 5005 (mode = ECL)

ECSWIN settings:
If ECSwin software is used, the “W&T-COMServer” option must be selected. Setup dialog for COM-4 (default settings):

TCP/IP Settings in the ECSwin Control Panel

All adjustable IP parameters are set via ECSwin software. All IP parameters and the statuses of COM-4 and COM-5 can be checked here in the status view.

Relays and S0 Relays (S0-OUT)

The U1604 basic module makes two S0 semiconductor relays (relay/S0-OUT 1+2) available:

U1604| Read/Write Status| Read/Write Relay
Mode
---|---|---
Relay 1 / S0-OUT 1| REL 1 or S0REL 1| RELM 1
Relay 2 / S0-OUT 2| REL 2 or S0REL 2| RELM 2
Relay 3 (prepared)| REL 3| RELM 3
Relay 4 (prepared)| REL 4| RELM 4
Relay 5 (prepared)| REL 5| RELM 5
Relay 6 (prepared)| REL 6| RELM 6

Comparison with U1601/3 summator (relays 1+2, S0 semiconductor relays 3 … 6):

U1601/3| Read/Write Status| Read/Write Relay
Mode
---|---|---
Relay 1| REL 1| RELM 1
Relay 2| REL 2| RELM 2
S0-OUT 1| REL 3 or S0REL 1| RELM 3
S0-OUT 2| REL 4 or S0REL 2| RELM 4
S0-OUT 3| REL 5 or S0REL 3| RELM 5
S0-OUT 4| REL 6 or S0REL 4| RELM 6

The S0 relays are laid out as NO contacts (max. 50 V DC, 20 mA, bipolar), and assignment of the value 1 causes the S0 relay to close.

Assignment is made as follows:

REL = {0, 1} RELM = is used to set the relay’s operating mode:

0 → always off
1 → always on
2 → changeable (default)

Relays 3 through 6 have been prepared – values can be assigned and settings can be selected, but they don’t have any effect.

U1624 – 12-Way S0 Input Module S0IN12

The twelve S0 measurement inputs are implicitly assigned to energy channels 1 through 64 via the TBUS address of the S0IN12 device.
This TBUS address is set by means of a rotary encoder which can be accessed after the module has been opened. The default setting is address 0.
If two or more modules are used, they have to be addressed differently!

TBUS Addresses	Energy Channels	Input Commands
0	1 … 12	1 … 12
1	13 … 24	13 … 24
2	25 … 36	25 … 36
3	37 … 48	37 … 48
4	49 … 60	49 … 60
5	61 … 64
(S0 inputs 5:5 … 12 unusable)	61 … 64

(S0 inputs 5:5 … 12 unusable)
5 … 15 (F)| Reserved

The following applies in general: Energy_channel_number = S0IN12_input_number
